How beta is 'Just For You' feature?

So during the presentation yesterday, Jobs said that the just for you recommendation feature is in beta right now. But on the Apple website, it is presented as a regular feature. I mention this because I don't seem to get a "just for you" section in the iTunes music store.

Is there a preference you have to choose somewhere to have it active? I have looked for it but haven't found it. This feature is something that I have been waiting for and I am a little bummed that I can seem to activate it.

yeah, I thought about that, but I am using the same old account I have had since I first downloaded iTunes. I checked my account info and found out that I have bought 562 songs... I would hope thats enough for iTunes to analyze and suggest more.

i kinda like it but i dont know how in the heck they recommend glen campbell because i purchased 2 shania twain songs?? i am NOT a country music fan. (i just liked those two songs of hers which are more pop than country) however some of the pairings are good and i will be buying more songs and albums due to "just for you"

Well, I don't know what the hell I am doing wrong. "Just for you" does not show up in my music store... sigh... stupid beta features. I hope that Apple doesn't go Google and keep this thing "beta" even after it becomes fully featured.

It shows up for me, and actually suggested a few songs that I ended up buying.

There is a link at the very bottom of the iTMS that says "Don't Show Just For You" section. For those not seeing it, I'd recommend looking for a link that enables it.

The only other reason I can think that it wouldn't show up for everybody is if there is a threshold number of purchases required. I've bought more than 800 songs on iTMS, so it's got a good database to work from.
